2. Description of the Related Art Conventionally, various tables with counters have been provided. For example, as disclosed in Japanese Utility Model Publication No. 2-32137, a support member having an upper edge as a stop portion is erected oppositely at both ends on one side in the depth direction of the surface of the table plate.
Rotating pieces fixed to both sides of a counter plate are pivotally attached to the support member, the counter plate is pivoted upward about the pivot point and mounted on a stop portion of the support member to be used as a counter. It is also possible to use it as a wide table by rotating it downward and flush with the table plate.

However, the above-mentioned table with counter is
When the counter plate is rotated downward so as to be flush with the table plate, the supporting member and the rotating piece of the counter plate remain in a protruding state on the table plate, which hinders the use as a wide table. There was also a problem in appearance.

Therefore, the inventor of the present invention has found that
As disclosed in Japanese Patent Publication No. 7, the supporting member rotates 180 degrees with respect to the table plate, and the rotating piece protruding from the lower surface of the counter plate slides with respect to the supporting member to form a table mode. At the same time, a table with a counter is proposed which has a structure in which no protrusions, that is, supporting members are left on the table plate.

[0005]

However, in the one disclosed in Japanese Utility Model Laid-Open No. 5-13227, the guide groove is formed continuously in an L shape along the two adjacent edges on the inner surface of the support member. Since a guide means is provided in which a pin that slides and engages with the guide groove is provided on the rotating piece that is provided on the counter plate so as to project outward, when the counter plate is moved from the counter mode to the table mode, Since it requires a two-step sliding operation along the L-shaped guide groove and a rotating operation in the middle thereof, it has a drawback that it is difficult to change smoothly.

In view of the above-mentioned situation, the present invention aims to solve the problems by not only realizing the counter mode and the table mode by moving the counter plate as in the conventional case but also the counter plate in the table mode. It is an object of the present invention to provide a table with a counter in which the supporting member does not remain on the table plate and the change between the two modes can be smoothly and easily performed.
